Improvement in fire-place grates



UNITED STATES PATENT FFICDE ALFRED GREENAWAY AND HUGH J. NEEDHAM, OF NEWALBANY, INDIANA.

IMPROVEMENT IN FIRE-PLACE GRATES.

Specification forming part of Letters Patent No. 116,438, dated June 27,1871.

To all whom it may concern:

Be it known that we, ALFRED GREENAWAY and HUGH J. NEEDHAM, of the cityof New A1 bany, county of Floyd and State of Indiana, have inventedcertain new and useful Improvements in a F ire-Grate and the Tile usedfor the back thereof, of which the following is a specilication: v

This improvement consists, more especially, in the grate and the tilethat forms the back.

The front part of this grate is made ot' iron, and hung on lugs on theinside ot' the grate` front, similar to those now in common use; but theends and back are formed by another grate, with perpendicular barsextending up as high as thefront, leaving an air-space of some three ormore inches behind the back and at the ends. The tileforming the back ismade to rest on the edge of the grate, pitching forward at the topaccording to the thickness of the arch at the top ofthe re-11 lace, theends being built in or closed with common tire-brick or tile made forthe purpose, leaving an air-space at the ends and back, between them andthe main walls of the nre-place, for the purpose of conducting all dustand ashes out through the due. The tile forming the back is made plainon the back side, straight across the lower edge, and somewhat in theform of a section of an ellipse, or flat arch at the top, the endsextending somewhat below what would be the center line, in order to suitthe height of the arch in different tireplaces when resting on the backof the grate. The inside edge of this tile has a beveled rim, aboutthree or more inches wide, raised about two inches high, around the top,extending down the ends, forming a part of the end walls of the grate;the central part of this last-named tile within the rim is made toproject in the center somewhat in the form of the section of ahemisphere, with the lower edge rounded olf where it rests on the backof the grate.

The great advantage which I claim for my invention is, first, the use ofa tile, the central part of which projects in front in connection withthe open-bar grate under it, which admits the air behind, causing theiire to burn clearly at that point, and not appear smothered ordeadened, as in cases where the concave or straight backs are used, andmade to pitch forward very much; I also claim the ilne or air-spacesbehind the grate as being a great advantage in conducting off all dustor ashes through the iiue, and also to give ample space for the ash-panunder the grate.

Having thus fully described the nature and object 0f my invention, amore complete understandingl of which may be had by reference to thedrawing. Figure l is a view of the front of the gra-te, showing the opengrat-e in the back, and tile above it. Fig. 2 is a sectional view ofthegrate and tile, showing the air-space behind it. Fig. 3 is anunimportant sectional view, simply showing the rest in the wall whichholds up the grate-back.

H is the front frame of the grate. C is the front part ofthe grate,suspended to the frame by the hook J at the top, the lower part restingon the spikeE underit. Two or more spikes maybe used, the heads or hooksof which being so placed as to come between the bars. B is the opengrate in the back, which also forms the ends, and is made withperpendicular bars, closed in smaller at the bottom than at the top soas to lap over and rest on the bottom of the front grate. A is the tilewhich forms the back above the grate, and when in position is made topitch forward at the top, leaving only sutcient hue-space between it andthe arch of the fire-place, and is held in its place by the brick thatis built in to close up the sides.

Gis the due-space in front. D D is the air-space in the back. K is themain walls of the tire-place. F is a rest in the same to hold up theback grate. L is the hearth.

Having thus fully described the drawing, what we claim as new, anddesire to secure by Letters Patent, is A The tile A, as above described,and the air-space D D behind it and at the ends, in combination with theopen grate-back B, when made separate from the front part; also, thefront 0, when hung to the frame H by the hook J at the top, and held upby the pin E at the bottom, when arranged, constructed, and operatedsubstantially as and for the purpose hereinbefore set forth.

ALFRED GREENAWAY. HUGH J. NEEDHAM.
